Enabling HDMI Output on Hackintosh with AMD Radeon Graphics

Getting HDMI output to work on a Hackintosh setup, especially with AMD Radeon integrated graphics, can be challenging due to macOS's native support and driver limitations. The complexity is further increased when dealing with AMD Ryzen CPUs, as they are not natively supported by macOS. Here's a guide to address the HDMI output issue:

Guide Step by Step:

1. Verify macOS Compatibility:

   • Ensure that your version of macOS supports AMD Radeon Graphics. Some versions have better support for AMD GPUs than others.

2. Update Your Kexts:

   • Update essential kexts like Lilu.kext, WhateverGreen.kext, and others that are relevant to your system. WhateverGreen, in particular, is crucial for graphics-related fixes.

3. Config.plist Settings:

   • Edit your config.plist file to ensure it's correctly set up for AMD graphics. This includes injecting the correct framebuffer and setting the right device properties.
   • You might need to experiment with different framebuffer personalities that correspond to AMD GPUs.

4. BIOS Settings:

   • Since you mentioned the dedicated GPU is disabled, ensure your BIOS is configured to prioritize the integrated AMD GPU.

5. Check Cable and Monitor:

   • Sometimes, the issue can be as simple as a faulty HDMI cable or compatibility issue with the monitor. Test with different cables and monitors to rule this out.

6. HDMI Audio:

   • If you also want to enable HDMI audio, you might need additional configurations in your config.plist and proper audio kexts.

7. Patch Framebuffer:

   • Depending on your specific GPU and macOS version, you might need to patch the framebuffer to enable HDMI output. This can be complex and requires a good understanding of your GPU and Hackintosh configurations.

8. Community Resources and Forums:

   • Check Hackintosh forums like tonymacx86, Reddit's Hackintosh community, or AMD OS X for users who might have a similar setup. They can offer specific advice or EFI folders that worked for them.

9. DSDT and SSDT Patches:

   • Advanced users might explore DSDT (Differentiated System Description Table) or SSDT (Secondary System Description Table) patching for more in-depth hardware configuration.

10. Monitor Resolution and Refresh Rate:

• In some cases, setting a specific resolution or refresh rate can enable the HDMI output. This can be done through system preferences or third-party tools.

Create config.plist:

For your specific issue with AMD Radeon Graphics, focus on:

• Graphics section: Inject the right values and check if iGPU is set up correctly.
• Boot Arguments: Add necessary flags that might help in initializing the GPU.
• Kexts: Ensure all required kexts for AMD graphics are in place.

Remember, the success of enabling HDMI output on a Hackintosh with AMD integrated graphics heavily depends on the macOS version, the specific AMD GPU model, and the Hackintosh setup. If you continue to face difficulties, consider reaching out to Hackintosh communities for more specific guidance based on your hardware configuration.
